Ok, I have a git with the master branch and a altered (twig) branch.
Right now they are in this way:
    Master Update - o  o -> Altered Twig Branch
                    |  |
                    | /
                    |/
  Master Original - o 
Right now, when I change the master, I need to manually incorporate the alterations on the altered twig. But the twig is heavily altered form from the master.
There is a ease way to do this? Or I need to incorporate manually?
